VL Pyörremyrsky (Wooden Messerschmitt), History
On 26 November 1942 the Finnish Air Force ordered two Pyörremyrsky prototypes to be built.
The aircraft were to be ready by May 1944. One prototype was later cancelled and only one
aircraft was ever built. The aircraft designation VMT Pyörremyrsky is also sometimes used,
as the factory had been formed into the State Metal Factories (Valtion Metallitehtaat) during
the construction of the aircraft. The Finnish Air Force airplane code letters PM gave the plane
nickname Puu-Mersu (Wooden Messerschmitt), but the plane was an independent design.
The use of wood in the construction of the aircraft was maximized due to the scarcity of metals.
The goal was to create a fighter with similar flight qualities to the German Messerschmitt
Bf 109G. The engine and the propeller were taken from the Bf 109G. The Pyörremyrsky
prototype PM-1 made its first flight on 21 November 1945 at Härmälä, piloted by Esko Halme.
The Pyörremyrsky design was considered quite successful. It could outclimb the Bf 109G-6
and it was very manoeuvrable. It was considered almost ready for mass production. Its only
major problem with the design was found to be the low-quality glue used in the joints.
The aircraft was still in the prototype stage when the war ended and this also meant that the
funds allocated for the project decreased. The Pyörremyrsky prototype was grounded after
only some 30 hours of flying and the programme terminated. The wing construction was
later used in another Finnish aircraft, the all-metal Valmet Vihuri trainer.

2. Create account, download
You will receive download link to all the zipped files to your email (please check your spam
folder if not) or you can log in to your account and download directly from our websites.
3. Gcodes preparing
option A Gcodes:
if your printer is i3 comptatible you can use prepared gcodes directly. Just save them to the
SD card and let the 3d printer do it‘s job. HE temperature is set to 230°C so the layers fuse
together well, you can adjust speed and temperature only through your printer‘s LCD. If these
Gcodes does not work for you, please proceed to the next options.

page 10
... print your plane | www.3DLabPrint.com
option B Factory files Simplify3D (recommended):
We prepared all you need in these files (FFF process settings, parts layout on bed, etc...)
You can use these settings as a start point. Adjust according to your need (adapt for your
printer), print single parts and so on... Most 3d printers should work just with these settings,
but please go through the settings and amend if necessary, we are not liable for any damage
resulting from using our settings. If this still does not work for you, please proceed to the
next option.
option C Simplify3D manual setting (watch and learn):
Use our video guide 2 and check our Simplify3D reference guide for proper setting... this
is very good option and you will learn a lot about Simplify3D and become an 3d printing
expert. Remember: We use 0 retraction with LW-PLA.
AND... please watch our VideoGuides:
video 2 Simplify3D setting
video about Thin Wall Printing (normal PLA)

page 11
... print your plane | www.3DLabPrint.com
option D CURA or MatterControl
MatterControl and CURA are free and provide satisfactory results. The airframe is still strong
enough, but don‘t expect the best quality. Both slicers lacks some very useful features, and
finer settings, like multiple processes according to Z height, retraction options, layer start,
etc.
Please try to find the best extrusion multiplier and temperature for good weight and best
possible layer bonding. Look at parts weight list for proper multiplier settings.
As a starting point you can use our predefined CURA or MC slicer setting file - see below
(always adapt it for your printer, change build volume, filament diameter, etc...
according to your printer!!!)
Please check our CURA guide on the website for the latest basic profile. Please visualise our
presliced gcodes to see how the result should look like and try to achieve the same in your
slicer. Remember: We use 0 retraction with LW-PLA.
Please watch our VideoGuides...

4. Print it
Save the Gcodes to the SD card and insert into your printer. Prepare your printer and start
printing, we prefer to use SD card rather than direct USB connection. Scaling the model will
lead to unusable result!
you will need: LW PLA filament - (by ColorFabb)
3DLac, Strong hair spray, PEI or your favorite adhesive bed surface
Razor blade
AND... please watch our VideoGuides:

Basic Tips and Advice
While stadard PLA filament could be used, this plane has been designed to be printed from
foaming LW-PLA by ColorFabb that means about 50% weight reduction on printed parts.
Please Experiment with temperature and extrusion multiplier. Hotend temperature is very
important (220° up to 260° celsius). The temperature determines, how much the LW-PLA
foams while printing. Cranking up temperature means, you can go loweron multiplier as the
material will gain on volume. Turn OFF cooling fan for better layer adhesion (HE fan should be
ON). We dont need it for thin wall printing. Heated bed is very recommended, 55-60° Celsius
(to prevent warping ends).
Price of the LW-PLA may look a bit steep at first glance, but since we’re using 50% less material
thanks to the foaming feature, the cost dierence is not so high as it looks.
LW-PLA by ColorFabb comes in two colours. White and Black. We found no dierence in
printing of both colours, but the black colour will probably attract the sunrays more, causing
warping of the thin wall surface. There are many 3d printers on the market, most of them are
capable of printing our airplanes (specific thin wall printing...) suficient volume, heated bed,
0.4mm nozzle.

Enjoy the fun together!
VL Pyörremyrsky is the first of new LW Planes
series designed for easy and cheap flying. The
build is simple even for a beginner. It’s very
low weight, easy assembly and fantastic flight
characteristics makes this model an ideal plane
for beginner RC pilots.
Very suitable for dads and kids. Children will learn
some modern building skills and technology and
most of all have fun. This is the reason, why every
dad should have a 3D printer at home.
This model has been completely designed with a
new LW PLA material by ColorFabb in mind.
Parts printed from this LW PLA are light, easily
sanded and glued together. This model requires
only about 220 g of this material, that means it’s a
very cheap build. In case of accident, parts can be
easily reprinted with just a filament cost.
We’ve been testing this material for half a year
before this plane was released... The material is
using an active foaming technology to achieve
lightweight, low density PLA parts. At around
230°C this material will start foaming, increasing
its volume by nearly 3 times.
All parts of this plane should be printed from LW-
PLA.
Possibly VL Pyörremyrsky can be printed from
normal PLA but the plane will be too heavy for
relaxed flying. Standard PLA printed model
therefore could not be recommended for
beginners. You should use heavyer battery also to
compensate Center of Gravity of the plane in this
case.

How to print LW-PLA?
The basic print setup is almost the same as we use for standard
PLA. The only dierence is in extrusion multiplier set to 0.5 and
turning o the retractions completely.
This results in parts with half the weight and still suitable
mechanical properties, but expect some heavy stringing inside
and outside. Of course you can try to tweak the retractions for
less stringing inside the parts, but there‘s a high risk of clogging
the nozzle or throat. Increasing the retraction distance above
1 mm is not recommended at all and leads to nozzle clogs
caused by foaming. Cleaning the hairy, but functional parts
after printing with retractions completely disabled seems to be
more ecient method. The nozzle is permanently pressurized
and you don‘t need to worry about print failures. This method
works fine even for bowden printers.
Extrusion multiplier 0,5 has been tested for easy print with
massive weight saving around 50%. Feel free to experiment
with extrusion multiplier and temperatures at will for the best
results on your printer.
Cosmetic issues of the prints are easily fixed with snap knife or
sand paper, as the LW is easily sanded and cut.

Glue fuselage parts F1-F4 with CA glue together. The new 3DLabPrint lock system will help you.
Zkontrolujte kolmost dílu F4 na uložení křídla dílů F1 a F2 před zalepením. Do not glue rudder
part before tail and elevator assembly. Use any hot tool to remove the unnecessary material
from F4 tail part for the elevator arm.
Insert two 90 mm long 3 mm diameter carbon rods making a rubber band wing holders. No
need to glue it for easy replacement.
For fuselage cover arm use a ball pen spring. Put it to the part 2 and glue with part 1 together.
NOTE: Don‘t glue the rudder tailpart yet !!! (proceed to the next step for elevator and stabilizer
assembly)

5.2.2 Fuselage tail - elevator pushrods and servos
Glue L1 and L2 parts of the stabilizer and elevator. The profile is symmetric, so the left and
right sides are identical. Glue the stabilizers perfectly perpendicular to the fuselage. Assemble
both sides of the elevator with the elevator control lever on a flat surface. Make a Z bend on
the elevator 0,8 mm pushrod wire. Using hot tool cut loose the hinge of the elevator on the
F4 part of the fuselage and mount the elevator assembly to the stabilizer using the 0,8 - 1,2
mm carbon rod or steel wire. Elevator should move freely controlled by the pushrod and
servo. Check the functionality of the elevator assembly carefully and finally glue in the rear
rudder part.

8. Painting/marking and Final assembly/setting
See video guide #7
Refer to your R/C system userguide for setup information.
See video guide #8
you will need: Your own Rx/Tx system
Install your reciever, connect battery, setup servos and etc. with your trasmitter, check servo
position, then install propeller, the supplied spinner guarantees proper cooling of the motor
and mount.
Make sure the battery is positioned properly and secured with wing battery holder, if battery
moves during flight it can shift the center of gravity backwards and aircraft will become
uncontrollable! Never set ESC with propeller installed, this could be very dangerous!
9. Go flying
Pre-flight check center of gravity is very important (move it 5mm forward for the first flights),
battery properly charged, ailerons and elevator deflection check, your own flying skills or RC
simulator training ...

... print your plane | www.3DLabPrint.com
10. Pilots Please Attention!
For the first flights we recommend setting the center of gravity to around 5 mm forward of
the CG tag - nose heavy, this increases the stability (you can use heavier battery). Increasing
expo settings on your transmitter for elevator and ailerons to 80 % calms response from your
stick inputs. Also you can decrease elevator and ailerons deflection to calm down the plane.
Make sure the battery is well fixed in proper possition. If it moves during flight it will cause
shifting of CoG aft and will result in uncontrolable flight behavior.
After gaining some confidence you can balance the plane to the Center of Gravity marks and
set Expos to 60 % as shown in the video/instructions... this gains back extra maneuverability.
Never fly aft positioned Center of gravity.
